Abstract

When remotely installing clients on a network, it is not possible to load the most popular 32-bit client operating systems from all of the most popular 32-bit server operating systems. Furthermore, when it is possible to load 32-bit clients, specialized driver and software are required, which use up valuable lower memory space on the client and require specialized client setup.

Enhanced Remote Network Installation

      When remotely installing clients on a network, it is not
possible to load the most popular 32-bit client operating systems
from all of the most popular 32-bit server operating systems.
Furthermore, when it is possible to load 32-bit clients, specialized
driver and software are required, which use up valuable lower memory
space on the  client and require specialized client setup.

      The described solution uses a hidden partition on the client
machine to contain a maintenance bootable version of the appropriate
operating system.  Typically, the client is a DOS client, and the
partition is of File Allocation Type (FAT).

      Software downloaded to the client searches for the hidden
partition using low level routines and if found, will indicate to the
server that the next time the client loads remotely, it will boot
from its own hardfile.  The client then alters its boot record
(Master Boot  Record (MBR)) to enable the hidden partition, which
will be one of four  permissible MBR entries.  The partition is
enabled by writing directly  to disk, so as not to affect the FAT
table, and the client then reboots  itself.

      The enabled partition is now booted and the client begins
remote installation, connecting to the server using a protocol and
installing or maintaining the desired operating system.  Upon
finishing installation, the maintenance partition alters the MBR,
hiding the partition until required a...
